After becoming a Mysterious Being, the Tongue Stretcher attacked some girls to make them "bear his children". Before he could do anything, however, he met the S-Class hero King. Hearing the famous "King Engine" and fearing for his life, the Tongue Stretcher immediately admitted defeat and while begging for mercy he started to cry and shake.[2]

Tongue Stretcher is later seen on a prison bus with other Mysterious Beings who were captured by heroes. When the other Mysterious Beings ask who he was captured by, he replies that he was captured by King, at which the other Mysterious Beings immediately look up to him for surviving a battle with the strongest man. He points to a bruise on his head, caused by a woman stepping on him, as a mark of vendetta against King and swears vengeance, but never sees the light of day again.[3]

Some time later, he is captured and held inside the Z-City complex along with other Wolf and Tiger threat monsters, but is soon killed.
